Dust-arrester.



TES PATENTQFFICE.

' JOHN incurrir,` 0F nl sUFFALo, NEW YORK.,

To all 'it may concelr:

- l Be it yknown that,v I, Joux Hunter, a citizen of thcY l h iitcd States, residing at ylluttalot. in thc 'county of Erie and State o Nervi York. have invented a new and useful Iniproveinent in Dust-Arresters, of which thefollowing is a specification.

'lhisinvention relates to dust. arresters or dust. collectors of that sort which coui-` w prise a group of spaced battles or detlectois through which dust-laden airor gas is.

caused to tlow alid which intercepts the dustand separates 1t from the air or gas.KY

The dust arrester forming the sub]ect of this invention is primarily intended ter use in .apparatus for the manufacture ofv sulfuric acid, and is located in the tine or passage through which the gases ,pass from the furnace to the acid clianibei's for-intercept- ,20 ing the ore dustcarried bythe gases and 1ers.

rcventing it from entering the acid chain'- however. limited to this use and may be einployedv for separating dust from. airand gases for an \"purpose.

The objecty of the invention is to produce an etiicient. and practical dust arrestery or collector of `this sort which is ot simple and economicalconstruction and in which the battles or detlectors are constructed and ai ranged in a novel manner whereby the dust will be etfectually separated from the air or gas and will be prevented from accoutulating on the battles or delict-tors so as to ,35 impede the passage 'of the :air or gas through 40 bodying the invention.

the dust arrester.

located and through which `the dust laden air or` gas passes. This chamber may, for

example, constitute a portion ofthe. gas

tine or passage connectinglr the furnace andv theacid chambers of a sulfuric acid manu-` factui'ing apparatus. Prefc'rahlythe portiona. of the tsie lcading'froin the furnace 'conn x.cts with the chamber A :it-'the bottom thereof, whilethe portion a of the tiue 'leading to the acid chambers connects with l the top of the chamber A. so that the dustupward direction through the dust arrester B between ther cross walls or partitions ul and u of the chamber..

Y 'lheedust ari-ester ll comprises a group laden air or gas is forced to fiow in an of parallel spaced battles or detiectors C which extend horizontally across the chainber 'in whichthey are suitably mounted, preterably in a supporting frame which is open at its top and bottoni for the passage.

The frame` of tlielair or gas through it. sliowiifcoiisists of opposite u right side plates i) connected b v cross rot Soi' bars (l and is supported uith itsside plates against the opposite z-ide walls of the chamber bv ledges d formed on these walls. The battles or delict-lors are supported at opposite cnds on suitable bearings or seats ou the side plate:` l) of the frame.

The bellies or detlcctors (l are arranged in staggered order in horizontal rows with the battles in one horizontal row opposite the spaces between the lialllcs in the next row. aiid the v are preferably ot' hollow scinifV convex upper surfaces of two adjacent baf- Y ties below before it can ascend through. the

spaces.between the battles of thc second row.

thc air or gas ascending between the. baiiles of each row being lbusd'ctlccteddown'wartlibi against the convex upper surfaces of these battles b v the battlesot' the next row above` before it ast-ends between these hitter baftles. The dust is thus separated from the air or gas and deposited You the convex uppersnri; t l l i.

`faces of the ibafiles, buton account of their convex or sloping upper surfaces the dust y will not accumulate on the balcs and chokeV the air spaces sufficiently to impede the flow of the airfor gas, but will fall from baille to batile into the bottom of the Adust-collect-l ing chamber. The .baiies or '(leflectovs can A be of other analogous shape having upper A Y stance, the battles can be of'inverted V-shape,

`downwardly a surfaces which will readily shed the'dustund under surfaces arranged so that the baies of one row will deflect the air or gas minst thc upper surfaces of the baiiles 1n` the next lower row, For inasrshown at.C in Fig. 7. t l

vProvision is made f-or rocking or cscillating the battles or detlectors from time to lrtime, should this be necessary, to dislodge Y any dust accumulating on the baes. For" this purpose the balllcs have'trunnions E at opposite ends adapted to Vrocli: in bearing seats e on the side plates of thesup ortingV frame, land as shown-in Fi 2 an 4, the l 'trunnions at oneend i the aiiles 'have slots e', or they may be otherwise fashioned, for the engagement of a key adapted to be in serted through holes e2 1n the adjacent sida late D for rocking the bales. As shown in 5 and 6, rock arms f are secured to the trunnions at one end of the batiies, therock arms of the bames in each row being ivoted to a connecting bar f' so that all of t e baffies in one row will be caused to rock to'- ether when one bnle is rocked. An 'open-l lng G closed by suitabledoors gis provided the operating device can beengag' with'the Y baliles -for rockin them. Any other suiti 1. In a dust arrester, the combination with s -a chamber, of a group of spaced battles arable means for in ependentlyl or collectively rocking the bales can be employed.

I claim es my invention:

rigged in rows 1n said chambcrwith the b es in 'one row above the spaces between the baies in the next lower row, said baflles having sloping,lr uppensurfaces which shed vthe dust Y and under surfaces which. slo e downwardly in opposite directions, whersoy the under surfaces of the battles in one rowr deflect they air or gas in opposite directions aga-mst the upper surfaces of the batlles in the next` lower row, rsubstantially as Vset I 2. In a dust arrester, the combination with n chamber, cfa group of spaced batlles arranged in rows in scid chamber with the lbullies in one row above the spaces between the' batlles in the iiext lower row,said bales i' i having convex upfer surfaces which shed 'the dust and conc .ve under surfaces which deflect the air or gas downwardly lin op osite directions' and beingkof greater .w1 th than the horizontal width of the spaces between the bafiles, substantially as set forth.

3. In a dust arrester, the combination with Y v i f a chamber through which the dust-ladenv air or pas moves upwardly, of a group of s aced hollow semi-cylindrical bales arrange hori--l zontally in staggered order across said chamber with 'their convex surfaces upward and with the concave under surface of one baille over the space between ad3acent lower j bafiies, substantlally as set forth.

4. In a dust arrester, the combination with a chamber, of a group of spaced bellies arrarped `in rows in said chamber with the ba es 1n one row abovethe spaces between' the bailles in the next lower row, said bafy fleshaving sloping upper surfaces which shed the dust and under surfaces arranged so thatthe baliies in one row deflect the air 'l or in. opposite directions against the baffles in the row below, and'means for rock` y 'y in saidbailles, substantially as set,v forth.`
